Kevin gathered data from his classmates about the number of books they consulted and the total time they spent on a research paper. The scatter plot shows the data he gathered and the line of best fit.
The equation of the line of best fit is y = 70.28x + 425.77.
Based on the line of best fit, approximately how many minutes would a student who consults 3 books spend on a research paper?
211
372
496
637
The student who consults 3 books spends 637 minutes on a research paper based on the line of best fit if the equation of the line of best fit is y = 70.28x + 425.77 option (D) is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
We have:
Kevin gathered data from his classmates about the number of books they consulted and the total time they spent on a research paper.
The line of best fit is:
y = 70.28x + 425.77
Plug x = 3 in the line of best fit:
y = 70.28(3) + 425.77
y = 21.084 + 425.77
y = 636.61 minutes ≈ 637 minutes
Thus, the student who consults 3 books spends 637 minutes on a research paper based on the line of best fit if the equation of the line of best fit is y = 70.28x + 425.77 option (D) is correct.

What is parallelogram?A Parallelogram is a four-sided quadrilateral whose opposite sides are parallel and congruent to each other.
The opposite angles of a parallelogram are equal.
These bisectors intersect each other at 90 degrees.
And it means that they are perpendicular.
Since they are perpendicular, we find that there 4 congruent triangles, XY is parallel to WZ, and WX is parallel to YZ.
Additionally, opposite angles are equal.
These two latter findings are the characteristics of the parallelogram.
Hence, the additional fact that would prove that quadrilateral WXYZ is a parallelogram is '' XY = YZ''.

On a game show, Celine is given the digits from 1 to 6 and has to use them to fill in a row with 2 spots. If the number formed is the correct price of the item displayed, she wins the item. Given that each digit can be used only once, how many 2-digit prices are possible?
Answer:
30 Two digits prices are possible.
Step-by-step explanation:
Celine was given numbers from 1 to 6
so the possible numbers are 1, 2, 3, 4, 5, 6
And we need to make a two digit number using these digits by using them only once
Using the box method of permutation
We have 6 possibilities on the tenth place of the two digit numberOn the One's place we will have 5 choices of numbers as one among these six given digits is used on the tenth place (Non repeating)So we will have total permutations = 6*5 = 30
Therefore 30 Two digits prices are possible.

Answer:
127 degrees
Step-by-step explanation:
If <1 is 53 degrees, then its vertical angle is also 53 degrees. Same side interior angles are supplementary which means they add up 180 degrees.
180 - 53 = 127
Michelle is debating between two different mortgages for $184,000. She found a 20-year fixed rate loan at 7.05% and 15-year fixed rate loan at the same rate. How much more interest will she pay for the 20-year loan versus the 15-year loan?
9514 1404 393
Answer:
$45,081
Step-by-step explanation:
The amortization formula can be used to find the monthly payment.
A = P(r/12)/(1 -(1 +r/12)^(-12t))
For the 20-year loan with r=0.0705 and P=184,000, the monthly payment is ...
A = $1432.08
The total amount repaid will be ...
12×20×1432.08 = 343,699.20
__
For the 15-year loan with the same parameters, the monthly payment is ...
A = 1658.99
and the total amount repaid is ...
12×15×1658.99 = 298,618.20
The difference in these repayment amounts is the difference in interest charges:
343,699.20 -298,618.20 = 45,081
The 20-year loan will cost $45,081 more than the 15-year loan.
Sally's job pays her $30 per hour.
If Sally works 6 hours, how much money would she earn?
I
Answer:
$180
Step-by-step explanation:
If Sally's job is paying her $30 PER HOUR, and we know that she works 6 hours, you would need to find how to put those two numbers together to get how much total money she earns. Since she gets 30 dollars per hour, and she works 6 hours, this hints to us that it is a multiplication problem. So, we would do 30×6= 180.

Answer:
59/6
Step-by-step explanation:
Multiply 3/4 with 1212 x 3 will become 36 and divided by 4 is 99 + 5/6 cannot be added because they do not have the same denominator.
